Food Poisoning.?

How do you know you have food poisoning or not?
What happens?
I never got it before so i was j.w.

depends on the severity of it.
Foodborne illness (also foodborne disease) is any illness resulting from the consumption of food. Foodborne illness is commonly called food poisoning, even though the physiological effects of foodborne illness are not always caused by poisons (toxins). True food poisoning occurs when a person ingests a contaminating chemical or a natural toxin, while most cases of foodborne illness are caused by a variety of foodborne pathogenic bacteria, viruses, prions or parasites that contaminate food. [1] Such contamination usually arises from improper handling, preparation, or food storage. Good hygiene practices before, during, and after food preparation can reduce the chances of contracting an illness. The action of monitoring food to ensure that it will not cause foodborne illness is known as food safety. Foodborne disease can also be caused by a large variety of toxins that affect the environment. For foodborne illness caused by chemicals, see Food contaminants.

Foodborne illness can also be caused by the presence of pesticides or medicines in food, or by unintentionally consuming naturally toxic substances like poisonous mushrooms or reef fish. Some could even come from the skin and nose, like staphylococcus aureus, which could lead to death.
Symptoms typically begin several hours to several days after consumption and depending on the agent involved, can include one or more of the following: nausea, abdominal pain, vomiting, diarrhea, gastroenteritis, fever, headache or fatigue. In most cases the body is able to permanently recover after a short period of acute discomfort and illness. However, foodborne illness can result in permanent health problems or even death, especially in babies, young children, pregnant women (and their fetuses), elderly people, sick people and others with weak immune systems. Foodborne illness is a major cause of reactive arthritis, which typically occurs 1鈥? weeks afterward. Similarly, people with liver disease are especially susceptible to infections from Vibrio vulnificus, which can be found in oysters or crabs. Typically food poisoning is evident when uncooked, or unprepared food is eaten.

The symptoms of Creutzfeldt-Jacob disease, transmitted usually by eating beef from animals with bovine spongiform encephalopathy (BSE, mad cow disease), are different from bacterial food poisoning and only appear after many years; the disease is fatal after symptoms appear.

Tetrodotoxin poisoning from reef fish and other animals manifests rapidly as numbness and shortness of breath, and is often fatal.


[edit] Incubation period
The delay between consumption of a contaminated food and appearance of the first symptoms of illness is called the incubation period. This ranges from hours to days (and rarely months or even years, such as in the case of Listeriosis or Creutzfeldt-Jacob disease), depending on the agent, and on how much was consumed. If symptoms occur within 1鈥? hours after eating the food, it suggests that it is caused by a bacterial toxin or a chemical rather than live bacteria.

During the incubation period, microbes pass through the stomach into the intestine, attach to the cells lining the intestinal walls, and begin to multiply there. Some types of microbes stay in the intestine, some produce a toxin that is absorbed into the bloodstream, and some can directly invade the deeper body tissues. The symptoms produced depend on the type of microbe.

Well when I got it, I was throwing up my food (even stuff that I ate like the day before) NON-STOP!! Not even for 5 minutes. Not kidding. It lasted from about 6 pm to 4 am...10 hours of nonstop spitting up!! And even when I got all the food up, I was like throwing up saliva...it was DISCUSTING!

you get very nauseous...diarrhea first, then throwing up..also you may be throwing up and have diarrhea at the same time..not a very fun the to have!
